Copper Nickel Finned Tube

Product Description

United Copper Industries specializes in producing copper-nickel finned tubes meticulously crafted from plain cupro-nickel tubes adhering to SB-111 UNS numbers 71500, 71000, 70600, and 70400/ ASTM B466. Our finning processes strictly adhere to SB-359 standards. These innovative finned tubes consist of bare Cupro Nickel, Copper, and Admiralty Brass tubes complemented by aluminum and copper fins. We proudly offer 90/10 copper-nickel and 70/30 copper-nickel finned tubes with plain ends customized to your specifications. Featuring an expanded surface area compared to standard tubes, our copper-nickel finned tubes significantly enhance heat exchange capacity, potentially leading to cost savings in fill volumes and materials. At United Copper Industries, we are committed to manufacturing bespoke copper-nickel finned tubes tailored to your unique requirements.

Copper-nickel finned tubes come in various designs to cater to specific applications and heat transfer requirements. Here are some common designs:

Longitudinally Copper-nickel Finned Tubes:

• Application: Best suited for situations where fluid flows on the outside surface of the tube parallel to its length.
• Fins: Fins can have a cross-sectional surface that is either tapered or flat, maximizing their efficiency.

Transverse Cupronickel Finned Tubes:

• Application: Commonly used in turbulent or gas flow applications, as well as in cross-flow heat and tube exchangers.
• Fins: Feature hollow metallic discs with equal spacing along the tubes length.

Extruded Cupronickel Finned Tubes:

• Optimum Temperature: Typically operates at a temperature of 285 degrees Celsius.
• Advantage: Known for offering excellent mechanical resistance to heat exchangers.

L Cupronickel Finned Tubes:

• Operating Temperature: Functions effectively within a temperature range of 150 deg C.
• Note: This type may have comparatively lower mechanical resistance.

Other Designs:

• LL Cupronickel Finned Tube: Specific design with unique characteristics.
• KL Cupronickel Finned Tube: Tailored for specific applications or performance requirements.
• G Cupronickel Finned Tube: Features and characteristics designed for specific use cases.

These various designs allow for customization based on the specific needs of heat exchanger applications, considering factors such as fluid flow, temperature requirements, and mechanical resistance. Each design has its advantages and is selected based on the intended use and operating conditions. Its essential to choose the right design to optimize the performance and efficiency of the heat exchanger system.

What are the Benefits of Copper Nickel Finned Tubes?

Enhanced Heat Transfer: The finned structure of these tubes significantly increases the surface area available for heat exchange. This improves heat transfer efficiency, making copper-nickel finned tubes ideal for applications where efficient heat dissipation or absorption is crucial.

Corrosion Resistance: Copper-nickel alloys, commonly used in these tubes, exhibit excellent corrosion resistance. This makes the finned tubes durable and well-suited for applications in harsh environments, such as marine and industrial settings where exposure to corrosive elements is a concern.

Adaptability to Various Environments: Copper-nickel finned tubes can withstand exposure to seawater, making them particularly useful in marine applications. Their resistance to corrosion and biofouling is advantageous in offshore and coastal environments.

Compatibility with Multiple Fluids: These tubes are compatible with various fluids, including seawater and brackish water. This versatility makes them suitable for applications in desalination plants, shipbuilding, and other industries where exposure to different types of fluids is common.

Longevity and Low Maintenance: The corrosion-resistant properties of copper-nickel alloys contribute to the longevity of finned tubes, reducing the need for frequent maintenance. This characteristic is especially beneficial in applications where accessibility for maintenance is challenging.

Customization: Copper-nickel finned tubes can be customized to meet specific size, dimension, and length requirements. This flexibility allows for tailoring the tubes to the unique needs of different applications, enhancing their versatility.

Savings in Materials and Fill Volumes: The increased heat exchange capacity of finned tubes may result in more efficient thermal performance, potentially leading to savings in fill volumes and materials. This can be advantageous in various industrial processes and systems.
